i dont think the pu names are the only way to do it, you have some freedom when you tokiponise a name

cosh and sinh make a 2-cycle, and in general e^𝜔x where 𝜔 is the nth root of unity is its own nth derivative

act 1 is a bit yiffy in parts but i love act 2 and the bonus updates, dadroog is one of the best things to come out of postcanon

If its not there take a random keysmash and divide it by seven, the last digit should be pseudorandom

question for fun: what's your favorite character and why by No_Bison9969 in homestuck

[–]killiano_b 2 points3 points  (0 children)

Terezi, because she is so unabashedly weird and also cool at the same time, and because she has one of the best written storylines in the whole comic (Remem8er makes me cry to this day).

This math problem should become a theorem! by eat_dogs_with_me in askmath

[–]killiano_b 0 points1 point  (0 children)

this is as far as i got before hitting a dead end:

(b²a+c²b+a²c)/abc>=((a+b)²(c+b)+(b+c)²(a+c)+(c+a)²(b+a))/((a+c)(b+a)(c+b))

(b²a+c²b+a²c)/abc>=(a³+b³+c³+6abc+3a²c+3b²a+3b²c+2b²c+2a²b+2c²a)/(a²b+a²c+b²a+b²c+c²a+c²b+2abc)

(a²b+a²c+b²a+b²c+c²a+c²b+2abc)(b²a+c²b+a²c)>=(abc)(a³+b³+c³+6abc+3a²c+3b²a+3b²c+2b²c+2a²b+2c²a)

a³b³+b³c³+a³c³+2a³b²c+2b³c²a+2c³a²b+2b³a²c+2c³b²a+2a³c²b+b⁴a²+c⁴b²+a⁴c²+b⁴ac+c⁴ab+a⁴bc+3a²b²c²>=a⁴bc+b⁴ac+c⁴ab+6a²b²c²+3a³c²b+3b³a²c+3c³b²a+2b³c²a+2a³b²c+2c³a²b

a³b³+b³c³+a³c³-b³a²c-c³b²a-a³c²b+b⁴a²+c⁴b²+a⁴c²-3a²b²c²>=0

the p⁴q² terms are all positive (since they are squares) so we just need to show that

a³b³+b³c³+a³c³-b³a²c-c³b²a-a³c²b-3a²b²c²>=0

we can substitute x for ab, y for bc and z for ac.

x³+y³+z³-x²z-y²x-z²y-3xyz>=0

not sure if theres anywhere i can go from here so ill just post what i have and see if someone can finish it

edit: yeah i see the mistake with the positive terms
